IIRC, this is a bug which shows only on systems having IPv6 support 
enabled. Make sure to add a IPv4 binding to your server, otherwise it 
tries to start listening socket for IPv4 and IPv6, which fails (or 
something like that; can't remember the exact details ..). However, 
following code solved my problems:

MyServer:=TIdTCPServer.create;
MyServer.DefaultPort:=8099;
MyServer.bindings.add.IPVersion:=Id_IPv4;
